The Pros and Cons of 3D Printers

Cons

The finished product is far From perfect, exhibiting 6 in addition to banding. In order to  7 desired, extreme care has to be taken in selecting the plastic filaments to be used. It is also necessary for plastic structures 8 during the printing process to avoid distorting the printed model.

Pros

Only a very 9 is required to produce 3D models. 3D products are also much cheaper to make than using normal manufacturing processes and need no storage space. In theory 10 of 3D printers to create virtually anything from pizza to fighter planes is astounding.

    Q8:  It is also necessary for plastic structures _____________ during the printing process to avoid distorting the printed model.

    Another problem is that the plastic structures have to be supported as they are laid down on the heated bed or they will distort or fall away as the plastic cools.

    Note: 

    The passage mentions that the plastic structures have to be supported as they are laid down on the heated bed (the printing process) or they will distort which means they need to be supported to avoid distorting.

    For that reason, the answer is to be supported

    Q10: In theory _______ of 3D printers to create virtually anything from pizza to fighter planes is astounding.

    In fact, the potential of 3D printers is jaw-dropping. The most ambitious plan yet for 3D printing has to be in the military field. If all goes to plan, fighter planes will at some, probably very distant, point in the future carry printers on board that during flight will be capable of printing out other fighter planes to replenish the flying squad. Admittedly, it takes a quantum leap of the imagination to accept that a machine that prints out clothing and pizzas will also be able to print out planes.

    Note: The answer must be a noun

    The passage mentions that in theory the potential of 3D printers is jaw-dropping (astounding) which prints out clothing and pizzas will also be able to print out fighter planes.

    For that reason, the answer is the potential

For the moment, however, the realisation of such projects remains in the 13 future.

  • 11 Answer: mainstream technology
  • Keywords in Questions

    Similar words in Passage

    Q11: Whilst 3D printing is far from becoming __________, so far experiments with the new technology have been promising.

    Note: 

    The passage mentions that whilst 3D printing is far from (meaning not yet) becoming mainstream technology until it becomes as much a part of the domestic furniture.

    Therefore, the answer is mainstream technology

3D Printers

Ever wished you could find a pair of shoes to match your outfit? Fancy a pizza but don't want to go out or wait for your delivery service to arrive? Simple. All you need is a 3D home printer. Whilst admittedly not yet mainstream technology, it is only a matter of time until the 3D printer becomes as much a part of the domestic furniture as the statutory TV or the washing machine. Currently, however, the technology remains firmly in the province of geeks and gadget lovers.

The design of the 3D home printer is nevertheless refreshingly simple. Its components are relatively few, and could theoretically be assembled by anyone with a rudimentary knowledge of mechanics and technological know-how. The 3 main elements of the printer are a metal framework which contains the mechanical part of the printer, a printer control board and a PC. The PC is connected via USB to the printer control board, which in turn is connected to the framework of the printer and attached to the side of the latter. A plastic filament of around 3m m in diameter feeds into the printer from an external source, connecting to the extruder motor inside the printer. During printing, the controlled movement of the extruder motor ensures the correct volume of plastic is used. The extruder motor in turn is connected to a heated extruder or 'hot end' that heats the plastic filament during printing. As the heated plastic emerges or is 'extruded' to use the correct terminology, it cools and is arranged in layers to create a solid 3D model.

In order to move the extruder about in 3D space, there are 3 axes, each controlled by motors. The X-axis motor, located in a midway position on the metal framework of the printer, moves the extruder left and right, using a pulley. The two Z-axis motors, which are located on either side of the heated printing bed, move the entire X-axis up and down via two threaded rods. The heated bed of the printer, which lies directly underneath the hot end of the extruder, is moved back and forth beneath the extruder by the Y-axis motor located underneath the heated bed. The bed is heated to around 70 degrees Celsius to ensure the newly laid plastic does not warp as it cools. Overall control of the printer is effected by the printer control board and the PC which contains the programme of the model that is being printed.

Once assembled, in theory it should be possible to print a 3D version of virtually anything. However, comparatively easy as it is to assemble, would-be DIY gadget enthusiasts should be warned that the printer has major technical limitations. The finished product will always have banding and surface detail remaining as evidence of how the model was laid down. In addition, operators of the printer have to be extremely careful not to knock it whilst the machine is in the process of printing, since this will end up in model distortion. Extreme care also has to be taken in the choice of plastic filament which will ultimately create the structure of the model. Some types of plastic may warp if the temperature is not controlled properly when the melted plastic leaves the nozzle, and later, when it is cooling on the bed. Obviously the 3D model will be the same colour as the plastic filament forming it, but colour limitations can easily be overcome by painting afterwards for a multicolour finish. Another problem is that the plastic structures have to be supported as they are laid down on the heated bed or they will distort or fall away as the plastic cools.

It is virtually certain, however, that such issues will be overcome in the future. The innumerable advantages of 3D printers far outweigh any disadvantages and justify time and resources spent on such technology. Firstly, the product can be produced on the spot within a very short time frame, thereby reducing time and cost of manufacturing by traditional means. Secondly, printing objects on a 3D printer removes the need for storage space of items since whatever is required is printed as and when necessary. Finally, despite expensive set-up costs, in the long run, 3D printing works out far cheaper than normal manufacturing processes since there is no longer a need for labour costs.

However, the 3D printer is still very much in its early stages and can be likened to early home computers which in technological hindsight now seem so cumbersome and slow. So far, early experimentations with the new technology have been impressive but not earth-shattering. Nevertheless, in the future that is all set to change. In fact, the potential of 3D printers is jaw-dropping. The most ambitious plan yet for 3D printing has to be in the military field. If all goes to plan, fighter planes will at some, probably very distant, point in the future carry printers on board that during flight will be capable of printing out other fighter planes to replenish the flying squad. Admittedly, it takes a quantum leap of the imagination to accept that a machine that prints out clothing and pizzas will also be able to print out planes. Sceptics, however, should remember that one of the forerunners to the modern computer, designed in the mid-twentieth century, filled an entire room, So, in theory, if we have come so far in a matter of years then who knows what the future may hold for 3D printers?
